105256-95-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 105256-95-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,2,5 and 6 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 105256-95:
(8*1)+(7*0)+(6*5)+(5*2)+(4*5)+(3*6)+(2*9)+(1*5)=109
109 % 10 = 9
So 105256-95-9 is a valid CAS Registry Number.

Synthesis of N-Substituted Prodigiosenes
Brown, David,Griffiths, David,Rider, Margaret E.,Smith, Rodney C.
, p. 455 - 464 (2007/10/02)
Prodigiosenes bearing N-methyl or N-benzyl groups in each of the three pyrrole rings have been prepared by coupling either a bipyrrole with a pyrrolecarbaldehyde or a bipyrrolecarbaldehyde with an α-free pyrrole.Synthesis via the bipyrrole route can lead
